(一)被测水温不能超过30℃ | (二)zui大允许工作压力(公称压力)为10Kgf/cm2(98×104Pa) | | (三)在zui大流量时,水表的压力损失不超过为1Kgf/cm2(98×104Pa) | | (四)从zui小流量量至不包括分界流量的低区的示值误差限:±5% 从包括分界流量至包括zui大流量的高区的示值误差限:±2% | | (一)The temperature of the water can't pass 30℃ |
(二)The rated pressure:10Kgf/cm2(98×104Pa) |
(三)The pressure lost in the water meter in Max flux ≤1Kgf/cm2(98×104Pa) |
(四)The show number error range form mix flux to the low district:±5% The show number error range form dividing line flux to the high district:±2% |

注:(1)公称流量是水表在规定误差限内允许长期工作的流量。 (2)始动流量是水表开始连续指示时的流量,此时水表不计示值误差。 (3)zui小流量是水表在规定误差内使用的下限流量。低于zui小流量时水表不能准确计量。 (4)zui大流量是水表在规定误差限内使用的上限流量。在zui大流量时,水表只能短时间工使用不至损坏。 | Note:(1)Rated flux is the permitted flux in the long work situation for the water meter. (2)Beginning flux is the flux at the moment the meter open, and this time, the meter can't accout the show error. (3)The Mix flux is the permitted Mix flux for the meter, if the flux is lower than this number, the meter will not to account correctly. (4)The Max flux is the highest flux for the meter in the rated error, at the max flux the meter only work in a short time and not to broken. |
